We have that:
A table of a function will have each input (domain) that has exactly one output value (range).
This means that a function can't have two different output that relates to an input.
Therefore, analyzing the given equations:
Option 1. Has an input value having different output values
Option 2. Has an input value having different output values
Option 3. Has an input value having different output values
Option 4. Has an exact output value that is related to every input value
Option 5. Has an exact output value that is related to every input value
Answer: Option 4 and 5
